9 Active listening is an important feedback in face to face communication, verbal cues like ‘uh huh’ or body language can provide feedback. However, online discussion lack of this kind of backchannels that demonstrate evidence of understanding. Feedback buttons like ‘thumb’ carry two functionalities: understand feedback and judge the statement. In this paper, the author…

7 This is a very interesting reading topic, can computers generate art. It started with the early age of photography and portraitures. At their beginning, both goal is to honestly reflect what is seen, at this phase, their use of documentation is higher than their use as a form of art. Then with the revolution,…

6 Summary The idea illustrated in this paper is very straightforward and practical in real world applications. The author designed a system that can capture design history and help improve the efficiency of such design process. In short, it is a snapshot system that help users quickly locate their past design sessions. Specifically, users collaborate…

5 Summary In this paper, the author discuss group work outcome quality on wikipedia through coordination. Two categories of collaboration was defined: explicit coordination, the editors plan the article through communication, versus implicit coordination, which subset of editors structure the work by doing the majority of it. The author’s assumption is that, in coordination intensive…

3 Summary In this paper, the author explored a interaction technique that can visualize multivariable dataset in VR environment, that he claim can bring rich and immersive experience. In the literature review section, the author claimed that several research support the view that projecting 3D data visualisations onto a 2D screen suffers from inherent issues…

8 Summary In the first paper, the author would like to study the problem of evaluating group brainstorming productivity and breadth. He proposed to observe the effect of internal diversity: cultural differences, and external diversity by supplying extra stimuli (pictures.) As for user study, two person groups were asked to perform 3 brainstorming tasks via…

4 WeBuild: Automatically Distributing Assembly Tasks Among Collocated Workers to Improve Coordination Summary In the first paper, the goal is to improve group efficiency and coordination. Specifically, participants was asked to complete manual assembly tasks, algorithm will assign subtasks to different collocated workers. They observed increased efficiency through reduction of startup time and overall time…

2 Summary In this paper, the author discussed introducing parallel prototyping during group creative design process and show better results compared to serial design. In traditional theories, parallel design have several benefits including: promotes comparison, encourages exploration, foster design confidence. The user study includes several key criterias, For example, the result can be measured objectively…

1 Summary In this paper, the author address the problem of analogy searching, which is effective when using one domain knowledge to solve problem in another domain, but this is difficult. The author designed 2 experiments, a set of 5 problems was defined and corresponding schemas was provided, then MTurks users was asked to find…

Idea 1, Nowadays, a lot of HCI applications rely on ubiquitous computing devices binded on individual persons. However, this approach can sometimes be limited and needs device reset when user is changed. Now with computer vision algorithms, we can use simple cameras to find and track person in an area, this result can be used…
